I want to overlay a scatterm plot over a world map.
The code is like:
ax = axesm('MapProjection','eqdcylin','MapLatLimit',latlim,'MapLonLimit',lonlim)
ax2 = axesm('MapProjection','eqdcylin','MapLatLimit',latlim,'MapLonLimit',lonlim)
load coastlines;
geoshow(ax,coastlat,coastlon ...);
scatterm(ax2,latcoord,loncoord...);
The problem is that the scatter plot is flipped so i need to flip it back.
But doing
set(ax2,'YDir','reverse');
Flips both the map and the scatter plot.
According to matlab documentation it is probably because only one axesm can be activated at a time.
How can i flip only the scatterm plot?

The solution was simple:
ax = axesm('MapProjection','eqdcylin','MapLatLimit',latlim,'MapLonLimit',lonlim)
load coastlines;
geoshow(ax,coastlat,coastlon ...);
scatterm(ax,fliplr(latcoord),loncoord...);

see this link for more or less same thing: http://in.mathworks.com/matlabcentral/answers/314877-adding-second-colormap-to-worldmap-figure
You define two axes like in the link and try to reverse.
Or reverse the data the way you want before plotting.

The question itself the user used two axis.

As the user noted, the final solution is not satisfying graphically.
